To all whom it may concern."

lie 1t known that I, JOHN S. SIMPSON, a

citizen of the United States, residing at Ingomer, in the county of Union and State of Mississippi, have invented certain new and useful linproveinents in Grosstrees for Telegraph-Poles, of which the following is a specification,

This invention relates to cross trees for supporting telegraph and telephone line wires, and one of the principal objects of this invention is to provide means of simple construction to supporting electrical conductors or wires upon a telegraph pole,' and to dispense entirely with the ordinary glass insulator; I

Another object of the invention is to pro vide 'a cross tree or arm having a block or series of blocks supported thereon, said blocks having interposed insulators for the line wires, said. insulators being entirely inclosed between the blocks and preferably formed of stone or similar inexpensive material.

The ordinary glass insulators on teleaph poles are constantly being broken by gunners in various parts ofthe country and by perso -s throwing stones at the cross trees or the telegraph poles, and to keep in good order a great many of these telegraph poles and insulators is a source of considerable expense. It was to overcome the objections above referred to that this invention was devised and to that end the insulators of H, 9 this invention are entirely concealed, or he with the outer surface of the cross tree, s tl the; cannot readily become 1n- }ured by nuschevious persons 'l oiogects advantages above rehe ferred to may he attained by means 0'1" the construction illustrated in the accompanying drawings, in which:
